How to Make a Homemade Concrete Countertop

Building a concrete countertop can be a weekend project for updating your kitchen. Its neutral color coordinates well with many color schemes, and its soft texture is safe for your family. Concrete countertops are also durable and will add personality, without breaking your budget.

Things You'll Need

Pine boards

Screws

Fiberboard

Caulk gun

Paste wax

Rebar

Cable ties

Wire

Concrete

Trowel

Hammer

Sealant

Build a frame to the dimensions of your desired countertop using 1-by-3-inch pine boards and screws. Cut the wood to fit a 3/4-inch fiberboard, and attach with screws.

Using a caulk gun, seal the corners of the frame. Apply one coat of paste wax to the inside of the frame.

Create a grid using rebar to fit inside the frame. Intersect the rebar pieces every 4 inches. Use cable ties to secure the rebar.

Place two 1-by-2-inch pine boards across the frame. Suspend the grid halfway up the frame by placing pieces of wire around the boards and rebar.

Mix concrete and pour it into the frame. Smooth the concrete with a trowel. Cut the wires and remove the boards laying across the top of the concrete.

Tap the edges with a hammer to fill any voids inside the concrete. Allow the concrete to dry for seven days, then remove the screws and boards. Apply two coats of sealer.

Tips & Warnings

For cleaning the concrete always use non-abrasive cleaners free of bleach or ammonia. Do not cut on your countertop because it will leave marks.
